The selectable options include one or more valid answers and one or more false answers. A user device is authenticated after correctly answering one or more presented authentication questions.

CROSS REFERENCE TO RELATED PATENT APPLICATION

This application claims priority to U.S. Provisional Application No. 62/219,377 filed Sep. 16, 2015, herein incorporated by reference in its entirety.

BACKGROUND

Authentication systems typically employ a password-based system to authenticate a user. As a user is registered with various systems and services, the number of passwords required for a user to remember increases. The user may also be inconvenienced as different services require differing policies for password construction, reuse, and changing. Additionally, for a given service, the same password is used repeatedly for subsequent authentication sessions if the password is compromised it can be reused for additional sessions by a malicious user.

SUMMARY

It is to be understood that both the following general description and the following detailed description are exemplary and explanatory only and are not restrictive. Provided are methods and systems for user authentication. An authentication system accesses multiple data points related to a user. These data points may include a transaction history, purchase history, social networking activity, or other data points. The authentication system presents a user with a series of questions based on these data points. Each question may be answered through a selection of one or more answers from a series of potential answers. To authenticate, the user must select the correct answers for each question. As the questions and the potential answers are dynamically generated, they can vary across authentication attempts. Thus, the specific set of answers provided by a user for a given authentication attempt are not applicable to subsequent authentication attempts. This provides increased security as a compromised set of answers for the given authentication attempt cannot be used by a malicious party to subsequently authenticate with the authentication system.

Additional advantages will be set forth in part in the description which follows or may be learned by practice. The advantages will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.

The present disclosure relates to a method for authenticating a user device with an authentication system. In an aspect, the authentication system accesses various transaction histories or other data points associated with a user account. For example, the authentication system may access a financial transaction history. The financial transaction history may indicate, for example, an amount of funds associated with a transaction, a vendor or merchant in a transaction, an indication of one or more goods or services associated with a transaction, or other data. The authentication system may also access purchase histories or order histories of third-party merchants. For example, a user may grant permissions or authentication credentials to the authentication system to access the third-party merchants. In an aspect, the authentication system may access social networking information or other user profiles to aggregate data points with respect.

Using the aggregated user data, the authentication service selects one or more answers to authentication questions to be presented to a user. For example, the authentication question may ask for a user to identify merchants or vendors from which the user has purchased within a predefined time period. The authentication question may also ask for a user to identify goods or services purchased within the predefined time period, having a price above or below a price threshold, or satisfying other criteria. Additionally, the authentication question may ask for an indication of relationships, interests, or other activities associated with a social networking account. The answers selected by the authentication service would serve as valid answers to the respective authentication question.

To authenticate a user device, a user is presented with one or more authentication questions and a pool of selectable options including both the valid answers identified by the authentication service, as well as false answers. In an aspect, the authentication service may be configured to randomly select the authentication questions from a pool of possible authentication questions. In a further aspect, the authentication service may be configured to randomly generate the pool of selectable options for each instance of presenting a given authentication question to a user. To authenticate the user device, the user must select the one or more valid answers from the pool of options. In an aspect, the user must select every valid answer present in the pool of options, and not select any of the false answers. In another aspect, the user may select a percentage or portion of the valid answers above a threshold, but not select any of the false answers. In a further aspect, the user may be presented with a series of authentication questions, and must correctly answer each of the authentication questions to be fully authenticated.

In one aspect of the disclosure, a system can be configured to provide services such as network-related services to a user device. FIG. 1 illustrates various aspects of an exemplary environment in which the present methods and systems can operate. The present disclosure is relevant to systems and methods for providing services to a device, for example, a user device such as a computer, tablet, mobile device, communications terminal, or the like. In an aspect, one or more network devices can be configured to provide various services to one or more devices, such as devices located at or near a premises. In another aspect, the network devices can be configured to recognize an authoritative device for the premises and/or a particular service or services available at the premises. As an example, an authoritative device can be configured to govern or enable connectivity to a network such as the Internet or other remote resources, provide address and/or configuration services like DHCP, and/or provide naming or service discovery services for a premises, or a combination thereof. Those skilled in the art will appreciate that present methods may be used in various types of networks and systems that employ both digital and analog equipment. One skilled in the art will appreciate that provided herein is a functional description and that the respective functions can be performed by software, hardware, or a combination of software and hardware.

The network and system can comprise a user device 102 in communication with a computing device 104 such as a server, for example. The computing device 104 can be disposed locally or remotely relative to the user device 102. As an example, the user device 102 and the computing device 104 can be in communication via a private and/or public network 105 such as the Internet or a local area network. Other forms of communications can be used such as wired and wireless telecommunication channels, for example.

In an aspect, the user device 102 can be an electronic device such as a computer, a smartphone, a laptop, a tablet, a set top box, a display device, or other device capable of communicating with the computing device 104. As an example, the user device 102 can comprise a communication element 106 for providing an interface to a user to interact with the user device 102 and/or the computing device 104. The communication element 106 can be any interface for presenting and/or receiving information to/from the user, such as user feedback. An example interface may be communication interface such as on/eh browser (e.g., Internet Explorer, Mozilla Firefox, Google Chronic, Safari, or the like). Other software, hardware, and/or interfaces can be used to provide communication between the user and one or more of the user device 102 and the computing device 104. As an example, the communication element 106 can request or query various files from a local source and/or a remote source. As a further example, the communication element 106 can transmit data to a local or remote device such as the computing device 104.

In an aspect, the user device 102 can include a display element 108. The display element 108 can include, for example, a monitor, capacitive or touch screen display, e-ink display, or other display as can be appreciated. The display element 108 can render a user interface 110 as will be discussed in further detail below.

In an aspect, the computing device 104 can be a server for communicating with the user device 102. As an example, the computing device 104 can communicate with the user device 102 for providing data and/or services. As an example, the computing device 104 can provide services such as network (e.g., Internet) connectivity, network printing, media management (e.g., media server), content services, streaming services, broadband services, or other network-related services. In an aspect, the computing device 104 can allow the user device 102 to interact with remote resources such as data, devices, and files. As an example, the computing device can be configured as (or disposed at) a central location (e.g., a headend, or processing facility), which can receive content (e.g., data, input programming) from multiple sources. The computing device 104 can combine the content from the multiple sources and can distribute the content to user (e.g., subscriber) locations via a distribution system.

In an aspect, the computing device 104 can manage the authentication between the user device 102 and an authentication service 110. In an aspect, the authentication service 110 may maintain a series of authentication questions 112 soliciting a user selection of one or more valid answers 114. The authentication questions 112 may be associated with one or more parameters or criteria that a given data point would satisfy, thereby being considered a valid answer 114. In an aspect, for a given user account, the authentication service 110 aggregates data from transaction histories, social networking profiles, or other data sources associated with the user account. The transaction histories may include, for example, financial transactions or purchases, and indicate goods or services purchased, vendors or merchants, prices, or other information. Data from the social networking profile may include interests, personal connections, group memberships, or other data as can be appreciated.

In an aspect, the authentication service 110 may aggregate data from services associated with the authentication service 110. For example, the authentication service 110 may be implemented to authenticate a user device 102 with a financial transaction service. The authentication service 110 may then have permissions to access the transaction history of the user with the given financial transaction service. In another example, a user may provide permissions, authentication credentials, or other data facilitating access to a third-party account or service by the authentication service 110. For example, a user may grant permissions for the authentication service 110 to access asocial networking account of a user. As another example, a user may provide authentication credentials for a third-party service to the authentication service 110. The authentications service 110 may then access application program interfaces (APIs) provided by the third party service, or parse content provided by the third-party service using the authentication credentials in order to aggregate the data for a given user.

In an aspect, the data aggregated by the authentication service 110 may be controlled according to user permissions. In an aspect, the user permissions may restrict a time frame, purchase amount, payment instrument, or other attribute of data that may be used by the authentication service 110. For example, user permissions may restrict the authentication service 110 to aggregating or using transaction data above a purchase amount threshold. As another example, user permissions may restrict the authentication service 110 to accessing transactions for a particular merchant or third-party service.

Using this aggregated data, the authentication service 110 identifies one or more valid answers 114 for a given authentication question 112. In an aspect, the authentication question 112 comprises a “yes/no,” “true/false,” or multiple choice question answerable based on aggregated data of a user. The authentication question 112 may have one or mime corresponding valid answers 114. For example, an authentication question 112 may solicit an indication of merchants from which the user has purchased in a predefined time period, e.g. the last week or the last month. The authentication service 110 may then identify merchants indicated in a given user's transaction history corresponding to the time period indicated in the authentication question 112. The identified merchants would then be defined as valid answers 114 to the authentication question 112 for a given user.

In another aspect, the authentication service 110 may have insufficient data to determine valid answers 114 for a given authentication question 112. For example, a new user may not have an associated transaction history. As another example, the authentication service 110 may not identify answers for a threshold number of authentication questions 112. In such an aspect, the authentication service 110 may receive indications of valid answers 114 for a given authentication question 112 from an authenticated user device 102. In such an aspect, the authentication questions 112 to which the user device 102 provides valid answers 114 may or may not be associated with transactional or social data as described above. For example, the authentication service 110 may request one or more pet names, travel destinations, or other information from a user. The provided valid answers 114 may then be used for authentication questions 112 in subsequent authentication attempts.

In an aspect, to authenticate a user device 102, the authentication service 110 may require a user of a user device 102 to answer one or more authentication questions 112. In an aspect, the authentication service 110 may select a predefined number of authentication questions 112 from a pool of authentication questions 112. The authentication service 110 may select the authentication questions 112 randomly, based on a frequency or last date of use of an authentication question 112, or according to other criteria. Thus, each attempt to authenticate a user device 102 may result in a different set of selected authentication questions 112.

For each selected authentication question 112, the authentication service 110 transmits an authentication question 112 and a pool of selectable answers to the user device 102. The pool of selectable answers can include one or more valid answers 114 and one or more false answers 116. In an aspect, the one or more valid answers 114 or false answers 116 may include an “all of the above” or “none of the above” answer. In an aspect, the authentication service 110 may select the valid answers 114 from a subset of valid answers 114 for a given authentication question 112. In an aspect, the authentication service 110 may select the false answers 116 from a subset of possible false answers 116. In an aspect, the false answers 116 may be derived from a pool of false answers 116 independent of a user account or user device 102. In another aspect, the false answers 116 may be derived from the aggregated data of for a given user account, and identified as a false answer 116 for not satisfying all of the criteria for a given authentication question 112. For example, an authentication question 112 may ask for a selection of items purchased in the past week. The authentication service 110 may identify as a false answer 116 an item purchased by the user outside of the past week. Thus, the false answers 116 presented for a given authentication question 112 vary depending on the user being authenticated.

In an aspect, the authentication service 110 may encode a user interface 109 for rendering by a display element 108 of a user device 102. The user interface 109 may indicate the authentication question 112, and include selectable elements 117 for each valid answer 114 and false answer 116. For example, the selectable elements 117 may include image selections or icons. In an aspect, the authentication service 110 may encode a text string as rendered text in an image. In an aspect, each selectable element 117 is of the same dimension. In such an aspect, the authentication service 110 may generate images for each selectable element 117 with additional bordering or image content to insure a same dimension In an aspect, each selectable element 117 is of a same data size. In such an aspect, the authentication service 110 may generate images for each selectable element 117 with additional bordering, image content, or non-displayed data such as metadata to insure a same file size. In an aspect, each selectable element 117 corresponds to an image including a randomly generated file name. In such aspects, the randomly generated file name, uniform dimension, and uniform size reduce the likelihood of file identification and cache vulnerabilities by malicious users.

A user input to the user device 102 selects one or more of the presented selectable elements 117 in the user interface 109, thereby selecting one or more valid answers 114 and/or one or more false answers 116. Based on the selected valid answers 114 and/or false answers 116, the authentication service 110 determines if the corresponding authentication question 112 has been correctly answered. In an aspect, the authentication service 110 may determine that an authentication question 112 has been correctly answered responsive to a selection of every valid answer 114 presented in the pool of selectable answers. In another aspect, the authentication service 110 may determine that an authentication question 112 has been correctly answered responsive to a selection of a number of valid answers 114 presented in the pool of selectable answers above a threshold. Thus, a user may need not select every valid answer 114 presented.

In an aspect, the authentication service 110 may determine that an authentication question 112 has been incorrectly answered responsive to a selection of any false answer 116 presented in the pool of selectable answers. In such an aspect, even if a user has selected the requisite valid answers 114, an authentication question 112 would be deemed incorrectly answered if one or more false answers 116 are selected. This reduces the vulnerability against brute force or random selection attacks.

In an aspect, if the authentication service 110 determines that an authentication question 112 has been correctly answered, the authentication service 110 determines if a requisite number of authentication questions 112 have been answered. If not, the authentication service 110 may then select another authentication question 112 for presentation to the user device 102. If the requisite number of authentication questions 112 have been answered, the authentication service 110 then establishes an authenticated session with the user device 102.

In an aspect, one or more network devices 116 can be in communication with a network such as network 105. As an example, one or more of the network devices 116 can facilitate the connection of a device, such as user device 102, to the network 105. As a further example, one or more of the network devices 118 can be configured as a wireless access point (WAP). In an aspect, one or more network devices 118 can be configured to allow one or more wireless devices to connect to a wired and/or wireless network using Wi-Fi, Bluetooth or any desired method or standard.

In an aspect, the network devices 118 can be configured as a local area network (LAN). As an example, one or more network devices 118 can comprise a dual band wireless access point As an example, the network devices 118 can be configured with a first service set identifier (SSID) (e.g., associated with a user network or private network) to function as a local network for a particular user or users. As a further example, the network devices 118 can be configured with a second service set identifier (SSID) (e.g., associated with a public/community network or a hidden network) to function as a secondary network or redundant network for connected communication devices.

In an aspect, one or more network devices 118 can comprise an identifier 120. As an example, one or more identifiers can be or relate to an Internet Protocol (IP) Address IPV4/1PV6 or a media access control address (MAC address) or the like. As a further example, one or more identifiers 120 can be a unique identifier for facilitating communications on the physical network segment. In an aspect, each of the network devices 118 can comprise a distinct identifier 120. As an example, the identifiers 120 can be associated with a physical location of the network devices 118.

FIG. 2 depicts an example user interface 200. The user interface 200 can be encoded by an authentication service 110 computing device 104 for rendering by a user device 102. Shown in the user interface 200 is an indication 202 of an authentication question 112 and a grid 204 of selectable elements 117. Each of the selectable elements 117 corresponds to a valid answer 114 or a false answer 116 to the given authentication question 112. A selection of the selectable elements 117 are greyed out, indicating their selection according to a user input. Also included in the user interface 200 is a button 206 that submits the selected selectable elements 117 to the authentication service 110.

FIG. 3 is a flowchart 300 depicting an example method. Beginning with step 302, the authentication system 110 receives an authentication request from a user device 102. The authentication request may include a username or other account identifier. The authentication request may also include a device identifying token corresponding to an account to be authenticated.

Next, in step 304, the authentication system 110 selects one or more authentication questions 112 to be transmitted to the user device 102. In an aspect, the authentication system 110 may select a number of authentication questions 112 defined in a user preference. In an aspect, the authentication system 110 may select the authentication questions 112 from a plurality of potential authentication questions 112. In an aspect, the authentication system 110 may select the authentication questions 112 from the potential authentication questions 112 according to a random process. In another aspect, the authentication system 110 may select the authentication questions 112 from the potential authentication questions 112 according to a frequency or recency of use, or other criteria.

After selecting the authentication questions 112, the method advances to step 306 where the authentication system 110 transmits one of the authentication questions 112 to the user device 102. The authentication system 110 also transmits a pool of selectable options for answering the authentication question 112. In an aspect, the pool of selectable options includes at least one valid answer 114 and at least one false answer 116. In an aspect, the at least one valid answer 114 may be derived from aggregated user data including transaction data, purchase or order histories, social networking data, or other data associated with a user and accessible by the authentication system 110. For example, the at least one valid answer 114 may correspond to one or more data points in the aggregated data satisfying criteria of the authentication question 112.

In an aspect, the at least one valid answer 114 transmitted to the user device 102 may correspond to a subset of valid answers 114 for a given authentication question 114. The subset of valid answers 114 may be selected randomly, or according to other criteria. Thus, for a given authentication question 114, the valid answers 114 are dependent on the user account being authenticated, as they are derived from user-specific aggregated data.

In an aspect, the at least one false answer 116 may be derived from the aggregated user data accessible by the authentication system 110. For example, the at least one false answer 116 may correspond to one or more data points in the aggregated data but failing one or more criteria of the authentication question 112. In a further aspect, the at least one false answer 116 may be selected from a pool of potential false answers 116 for a given authentication question 112. In an aspect, transmitting the authentication question 112 and selectable options may be performed by encoding a user interface 109 for rendering by a user device 102. The user interface 109 may include a collection of selectable elements 117 each corresponding to one of the selectable options for the given authentication question 112.

Next, in step 308, the authentication system 112 receives the selected answers for the transmitted authentication question 112 from the user device 102. In an aspect, the selected answers correspond to selected ones of the selectable elements 117 in the user interface 109 transmitted to the user device 102. In step 310 the authentication system 110 determines if the authentication question 112 was correctly answered. In an aspect, the authentication system 110 determines that the authentication question 112 was correctly answered in response to each of the valid answers 114 presented to the user being selected and having none of the false answers 116 being selected. In an aspect, the authentication system 110 determines that the authentication question 112 was correctly answered in response to a number of valid answers 114 above a threshold being selected and having none of the false answers 116 being selected.

If the authentication question 112 was incorrectly answered, the method advances to step 312 where the authentication request is denied. If the authentication question 112 was correctly answered, the method advances to step 314. If there are additional selected authentication questions 112 to be answered, the method returns to box 306 where a next authentication question 112 is transmitted to the user device 102 for answering. Otherwise, if all of the selected authentication questions 112 have been answered, the method advances to step 316, where the authentication system 110 establishes an authenticated session with the user device 102.

FIG. 4 is a flowchart 400 depicting an example method. Beginning with step 402, a user device 102 receives an authentication question 112 and selectable options for answering the authentication question 112 from an authentication system 110 in order to establish an authenticated session. In an aspect, this may include receiving data encoding a user interface 109 including the authentication question 112 and multiple selectable elements 117 each corresponding to a selectable option. In an aspect, the selectable elements 117 may correspond to at least one valid answer 114 and at least one false answer 116.

Next, in step 404, the user device 102 receives user input to the selectable elements 117 indicated selected answers to the authentication question 112. In step 406 the selected answers are transmitted to the authentication system 112. A response to the transmitted answers is received from the authentication system 112 in step 408. At step 410, if the response includes a follow-up authentication question 112, the process returns to step 404, where the user device 102 continues to answer authentication questions 112. If, at step 410, a response other than an authentication question 112 is received, the process advances to step 412. If, at step 412, the response indicates a failed authentication, the process advances to step 414, where the authentication system 112 denies authentication and the current authentication attempt ends. Otherwise, the process advances to step 416 where the user device 102 begins an authenticated session, having successfully answered the requisite number of authentication questions 112.

In an exemplary aspect, the methods and systems can be implemented on a computer 501 as illustrated in FIG. 5 and described below. By way of example, computing device 104 of FIG. 1 can be a computer as illustrated in FIG. 5.
